✦ Synopsis


AbStl ¶lCt

Collision-induced dissociation (CID) of highly excited NOs in the mixed 2A,/2B2 electronic system has been observed for well characterized MgO ( 100) surfaces with parent and product angular resolution at various internal energies. NO state distributions were probed by two-photon, two-frequency ionization, and its yield was found to track the NO2 absorption spectrum, confirming the CID mechanism. The angular dependence of the NO state distribution indicates that CID occurs following direct inelastic scattering rather than trapping-desorption.
